PAH calibration
The PAH sensor can be re-calibrated with a two-point calibration procedure. The two-point calibration consists of an
offset calibration and a scaling calibration. The calibration must be performed with a DryCal-0 for offset, a DryCal-1 for
scaling by following the procedure as described in this section .
Tools needed for PAH calibration:
Spanner size 13
DryCal-0
DryCal-1
Lint free cloth and clean water
Incorrect calibration always leads to incorrect measured values. Always use a DryCal-0 and DryCal-1 paired with the
specific PAH Sensor when calibrating to prevent an incorrect calibration.
Switch off the power for the WSU pumps, close all isolation valves for the WMS system and drain the measurement
chamber before starting the PAH calibration.
